Python pip install fails: invalid command egg_info

Install distribute, which comes with egg_info.

Should be as simple as pip install Distribute.

Distribute has been merged into Setuptools as of version 0.7. If you are using a version <=0.6, upgrade using pip install --upgrade setuptools or easy_install -U setuptools.

As distribute has been merged back into setuptools, it is now recommended to install/upgrade setuptools instead:

[sudo] pip install --upgrade setuptools

Bear in mind you may have to do pip install --upgrade Distribute if you have it installed already and your pip may be called pip2 for Python2 on some systems (it is on mine).
